Remote Access Solutions
Remote access
Remote access is defined as the ability of a user to log onto a network from a distant location. This is accomplished with a remote computer connected to the distant network. Whereas remote control refers to taking control of another computer, remote access means that the remote computer becomes a work station on the network. Communication between the network facility equipment and the remote computer is accomplished through a data link. The only difference between a remote user and workstations connected directly to the network is slower data transfer speeds. Remote Access is also useful when you want to connect local office computers with corporate networks. This allows the business to share resources as if all computers are connected to the same LAN. Two common methods of providing this type of remote access are dial-up and Virtual Private Network (VPN).
Dial-up remote access is when a client uses the telecommunications infrastructure to create a physical connection with a remote access server, which is attached to a Local Area Network (LAN). The physical or logical connection between the remote access server and the remote access client is made possible through dial-up equipment. Dial-up remote access is considered a private communication portal. The nature of the dial-up equipment and WAN infrastructure varies, depending on the type of connection. There are several telecommunications technologies can make up the WAN infrastructure used in dial-up remote access. These technologies include Plain Old Telephone Service (POTS), T-carriers, Integrated Services Digital Network (ISDN), Asynchronous Transfer Mode (ATM), and Digital Subscriber Line (DSL). The remote access software dials in...

...anization cannot ensure who use telecommuter computers and what happen in remote location. It's also too difficult to ensure telecommuter follows the Non-Disclosure Agreement. There is a way that IT department can use to prevent this from happening. They can control the remote computer settings, and monitoring employee perform on the computer. The deep Freze program can be used to prevent telecommuter to change computer settings. Other than that, keystroke recorder can monitor activity telecommuter so that they engaged with the company work. The last categories of technical support is communication and logistical support. For the communication, IT department responsible to provide support for telecommuters by operating communication and groupware tools for business such as e-mail, instant messaging, and chat room that provide means of communication.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
These technologies are of limited effectiveness in connecting employees while at work and at home via Berean network. Berean¡¦s infrastructure does not allow employees on the move to leverage the time they spend at meetings, in the cafeteria, and the other location to catch up on e-mail, retrieve information, or perform other work related activities (Sage Research Staff, 2005).

The computer is considered one of the most important technological advances of the twentieth century. Security and privacy issues have been in existence long before the computer became a vital component of organizations' operations. Nevertheless, the operating features of a computer make it a double-edged sword. Computer technologies with reliable error detection and recording capabilities, permit the invasion of a supposedly secure environment to occur on a grand scale and go undetected. Furthermore, computer and communications technology permit the invasion of a persons' privacy and likewise go undetected. Two forces threaten privacy: one, the growth of information technology with its enhanced capacity for surveillance, communication, computation, storage and retrieval and two, the more insidious threat, the increased value of information in decision making. Information has become more vital in the competitive environment, thus, decision makers covet it even if it viol!
The nature of our business requires us to have a flexible sales force. Because of that detail we need to be receptive to the needs of our mobile workforce. The most critical tool involved in their success is the ability to reliably connect and access our company networks. These connections can be from employees using company issued laptops or personal computers used from home or on the road.
The workplace today goes beyond just the walls and ceilings that surround an office environment or office building. According to the International Telework Association and Council, 44.4 million Americans worked from home at least part of the time in 2004, up 7.5% from just on year earlier (Earthweb, 2005). Though it may be very convenient to work from home, the choice can bring its own set of problems. There are financial reasons, efficiencies, and even managing time are just a few to name that bring about many challenges and issues that any remote employee would face in that type of work environment.
Digital Subscriber Line new technology that takes advantage of standard copper telephone line to provide secure, reliable, high-speed Internet access. DSL refers to the family of digital subscriber line technologies, such as ADSL, HDSL, and RADSL. Connection speed for DSL ranges from 1.44 Mbps to 512 Kbps downstream and around 128 Kbps upstream. Unlike traditional connections DSL such as analog modems and IDSN, DSL deliver continuous “always on” access. That means multimedia-rich websites, e-mail, and other online applications are available anytime. DSL makes it possible for you to remain online even while you’re talking on the telephone-without jeopardizing the quality of either connection. DSL is available in a spectrum of speeds. Some are best home use, while others are designed to accommodate rigorous business demands. Whether for business or the home, DSL, offers unsurpassed price/performance value compared to other online options. There are the five facts that one should know about DSL. It is remarkably fast. With DSL service, you can benefit from Internet speeds that are up to 12 minutes faster than a typical ISDN connection and 50 times faster than traditional 28.8 Kbps modems. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same with a traditional 28.8 Kbps. It’s highly reliable. One can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. It’s inherently secure. DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-upp modems or cable modems. DSL protects your valuable data with the most secure connection available. It’s surprising affordable. DSL is widely recognized as the most cost-effective connectivity solution for small buisness. DSL delivers industrial- strength like speed to multiple users at only 25% of typical TI costs. There is no better price option available. DSL is also an exceptional value for home users. At about $2 a day for services that meets the needs of most people. The connection is always on. It’s ready to run every minute of the day. There’s no more logging on and off. No more busy signals or disconnects. This gives you the freedom to focus on what you want to accomplish on line rather than focusing on trying to get connected.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
